MB, I’ll take a few close ups tomorrow. Each arc is 2 lengths of bamboo. I’m using the tops of the plant for the angled loops. Most of the bamboo is around 1″ to 3/4″ diameter tapering to 3/8″, 12 feet long. I got the bamboo free from people that had it in their back yard and were being forced to remove all of it, because it was spreading into the neighbors yards. Each piece was about 20′ long and 1.5″ diameter at the base. I’m using the thicker pieces for poles and rails.
